SCALE-BEAM.

SPECIFICATION forming part of Letters Patent No. 242,465, dated June '7, 1881.

Application tiled Novemberl 8,1ESO.

To alt whom it may concern Bc it known that I, THOMAS F. MOKEE, a citizen of the United States, residing at Bloomville,in the county of Seneca and State ofOhio, have invented a new and useful Weighing- Scale, of which the following is a specification.

My invention relates to improvements in weighing-scales in which graduated balancebeams and sliding poises are used, as will be hereinafter' fully described; and its objects are to adapt the scale to indicate the different items of which a load may have been composed, or the different items which havebeen taken away from an original load upon the scale-platform, these indications being made either in pounds, or in dry measure, or in liquid measure, or in all together. These objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an elevation of a platform-scale of my improved construction. Fig. 2 is a detail view of the main beam and its auxiliary beams, the latter being shown in reversed positions. Fig. 3 is a detail view of one ot' the bridge-pieces which hold the auxiliary scalebeams to the main beam. Fig. 4 is a section in the line x of Fig. 2. Fig. 5 is a detail view ot'an end portion of one of the auxiliary beams, a longitudinal section of a poise, of a portion of the bridge, and of the fastening-nut. Fig. 6 is a detail view of a bridge-piece made to hold four auxiliary scale-beams, and Fig. 7 is a detail view of a bridge-piece made to hold two auxiliary beams.

Similar letters refer to similar parts throughout the several views.

In the drawings, A represents a frame; B, a platform; C, the main beam, c the suspending-rod, and c the draft-rod, of my improved weighing-scale. l

The main beam O is provided with two scales, c2 c3, the upper scale, c2, being graduated from the left to the right hand, and the lower scale, c3, being graduated from the right to the left hand. At the beginningof each of these scales a poise, D and D', is provided, as shown, which poises tit loosely around the beam. The opposing faces of these poises are cut out, as at d, for the purpose of exposing and pointing out the graduations of the scales.

(Model.)

The main beam O is also provided with two transverse inclined bridge-pieces, E E, which are attached to the beam, by means of vertical slots c and set-screws c in such manner that the one is near the end of the beam, while the other is near its fulcrum c4. Between these bridge-pieces a number of auxiliary wei ghin gbeams, F Gr II, are supported by means ot'journalsfg h passed through holes c2 in the bridge- 6o pieces E, and fastened to them by means of thu mb-n uts c3. By this construction these auxiliary beams can be turned or reversed so as to exhibit their opposite sides and the graduated scales thereon, and they can also be turned at 6 5 such an angle as to greatly facilitate the reading of that which is marked thereon.

Each of the auxiliary beams F and G is on cach side provided with two scales graduated in opposite directions, similar to those on the 7o main beam C, and with a pair of poises, f f2 g g2. These graduated scales may be adapted to indicate less weight than those on the main beam O, or the fractions ot' pounds, or the bushel-measu res for wheat, corn, or other grain, 7 5

and so on.

In the accompanying drawings, the beam F, as in Fig. 1, is provided on one side with two scales, f3 j, in reverse directions, indicating the number of bushels of corn added to or taken 8o the platform, while the other poise, fg indi- 9o cates in a similar manner the number oi' bushels and their weight taken away from the platform.

The beam G is similar to the beam F. It has two scales, g3 g, on one of its sides, as in Fig. 95

l, grad uatedin opposite directions, for the purpose of indicating bushels of wheat, and two scales, g5 g, as in Fig. 2, on its opposite side, for indicating their weight in pounds.

The beam II is provided with two poises, h 10o h2, and has on one side, as in Fig. 2, four scales, h5 It hT h, the upper two of which indicate 1n Thus, the poise opposite directions the bushels of wheat, and the lower two, in a similar manner, the bushels of corn weighed on or weighed off, and 'on the other side, as in Fig. l, two scales, h3 ht, showing the weight in pounds placed upon or taken from the platform. This beam H is adapted to weigh much greater weights than the beams F G, and consequently has different scales and larger poises than the beams F G.

The main beam C has the heaviest poises, and is used to weigh bulks upon the platform after they are increased by additional bulks or decreased by removing portions thereof. The poises used on the auxiliary scale-beams F G H have their opposing faces shaped similar to those of the poises D D', and for the same purpose.

In the drawings, the scales c2 c3 are graduated from 0 to 5,000 pounds; the scales f3 j, from 0 to somewhat over S bushels cornuneasure 5 the scales g3 g4 from 0 to somewhat over S bushels wheatmeasure 5 the scales h3 h4, from 0 to 2,500 pounds; the scales fff", (coinciding` with the scales f3 ft) from 0 to 500 pounds; the scales g5 g, (coinciding with the scales g3 g4,) from l0 to 500 pounds; the scales h5 h6, (coinciding with the scales 7b3 h4,)from 0 to somewhat over 40 bushels wheat-measure, and the scales h" hg, (coinciding, also, with the scales h3 h4,) from 0 to somewhat over 40 bushels corn measure, the graduations for bushelmeasurement of corn and wheat being in accordance with the standard weight of the grain-viz., ftysix pounds for one bushel of corn, and sixty pounds for one bushel of wheat.

Operation Previous to weighing all the poises are moved to their normal positions, as represented in Figs. l and 2, or, in other words, the poises D f g lt of the upper or adding scales, c2 f5 g5 h5, as in Fig. 2, are moved to their extreme left-hand position, and the poises D f2 g2 h2 of the lower or subtracting scales are, as in Fig. 2, moved to their extreme right-hand positions. Theload to be weighed is now deposited upon the platform B and weighed by moving the poise Dto the right until the scale is balanced, whereby the correct weight of the load is indicated by the poise D. If, now, a portion of this load is to be removed from the scale, the poise D is moved to the left until it points to the desired number, whereupon so much of the load on the platform is removed as will cause the scale to be balanced again. This mode of operation applies also to the auxiliary scale-beams F G H, as will be seen. For example, a wagon-load consisting of wheat, corn, and meat is to be weighed The wagon is moved upon the platform B, and the gross weight ascertained, in the usual way, by ineving the poise D to the right until the scale is balanced, when it will point, say, to 4,500 pounds. From this load seven bushels of wheat are to be removed. The poise g2 is now moved to the left until it points to 7 on the scale g4. The wheat is now removed until the scale becomes balanced. Again, if eightbushels of corn are to be removed, the poise f2 is moved to the left until it points to S on the scale f, whereupon the corn is removed until the scale becomes balanced again. Finally, one thousand tive hundred and fifty-sixpounds of meat are to be removed, and the poise h2 is now moved to the left until it points to 1,556 on the scale ht. Themeatis then removed until the scale becomes balanced again. This done, the poises D f2 g2 h2 exhibit now the full numbers 4,500 pounds gross weight, and therefrom removed eight bushels of corn, seven bushels of wheat, and one thousand tive hundred and iftysix pounds of meat, which is re corded bythe dealer in his book.

If the weight of all the articles removed is to be ascertained, the poises fzg2 h2 are returned into their normal positions, and the poise D is moved to the left. At 4,500 of the scale c2 the poise D meets with the poise D, and as one poise must remain at that point the poise D' is left -there and the poise D is moved to the left until the scale is balanced. It will now be found to point on the scale c3 to the amount in pounds of the removed corn, wheat, and meat. The poise D' may now be moved back to its normal position, and the weight of the remaining load on the platform be ascertained by means of the poise D and scale c2, in the usual manner.

In a similar manner loads of certain or given weights may be added to a load on the platform, ora number of loads ofdifferent character may be placed upon the platform and weighed singly and together, by using the poises j" g h D and the scales f3 g3 h3 c2 in Fi 0'. l.

' By turning the auxiliary beams F G of FiO. l over, other scales on F and G are exhibited, as in Fig. 2, for different use, the scales f5 f U g5 g in said Fig. 2 indicating pounds in comparatively lesser number and fractions of pounds graduated in opposite directions, and in the same manner the beam H (shown as in Fig. l) may be turned over as in Fig. 2, in order to exhibit thc grain-scales h5 hj h7 la, by which greater bulks of grain can be weighed on or off than by the scales f3 fA1 g3 g", as shown in Fig. 1.

In applying my invention to practical use I will employ such number of auxiliary beams as I deem necessary to serve the varying requirements of the purchasers.

I do not limit myself to the above-described special scales, as I intend to graduate scales for all kinds of dry and other measures, such as measure of fruit in either dry or fresh condition, seeds, meals, and so 011. Likewise, the construction of scale frames and receivers will be different, according to the use to which they are to be applied. In other words, I will apply my double reversible scales to the heaviest weighing, and my lightest-weighing scales to platform-scales or grocers scoops, and so on.

In some cases the use of auxiliary beamsmay be dispensed with, andthe main beam, havin g IOO IOS

two poises and two scales, graduated in opposite directions, as described, may be employed but for general uses a main beam combined with one or more auxiliary beams will be found most desirable.

I claim- 1. In combination with a Weighingbeam graduated in opposite directions, one or more auxiliary revolving beams alternately graduated in opposite directions and having each two poises, substantially as and for the purpose set forth.

2. In a Weighingscale, a single weighingbeam which is provided with graduatons num-
